objective: in all ceramic fixed partial dentures the connector area is a common fracture location. the survival time of three-unit fixed partial dentures may be improved by altering the connector design in regions of maximum tension. the purpose of this study was to determine the effect of buccolingual increase of the connector width on the stress distribution in posterior fixed partial denture...

A procedure is described for fabricating an immediate complete overdenture where several teeth retain an interim fixed partial denture (FPD) until the complete denture is finished. Nonessential posterior teeth were first extracted. An interim fixed restoration was fitted to five strategic teeth, and the four maxillary incisors were reduced to the gingival margin. The reduced teeth and the maxil...

A soft tissue drape that is formed around the tooth, as it emerges from bone, has both aesthetic and functional significance. Post-extraction hard changes are inevitable leads to a buccal concavity. The pontics for tooth or implant supported fixed partial denture in such cases appear longer. Preservation of part root preserves periodontal apparatus hence facilitates optimal region pontic site d...

statement of problem: the connector area is the weakest zone of an all-ceramic fixed partial denture (fpd), where most catastrophic failures of the prostheses tend to occur. purpose: the aim of the present study was to assess the effect of the convergence angle of abutments on the fracture resistance of three-unit fixed partial dentures made of ips-empress2. materials and methods: forty extract...

objective: this in vitro study evaluated the fracture strength and bending amount of twotypes of fiber reinforced composite (frc) and cast metal frameworks used for fabrication of inlay fixed partial dentures (ifpds). materials and methods: seventy-two extracted first maxillary premolars and molars (36 each) were embedded in acrylic resin to represent a missing of second maxillary premolar. frc...

Osseointegration emerged in the 1950s, created by Per-Ingvar Branemark, when it was conceptualized as an intimate connection between implant and surrounding bone, with this discovery, proposed a treatment for total or partial edentulism. implants supported. Excessive loads generated poor adjustment of occlusal forces are recurrent common, may generate resorption supporting bone; situations exce...

Materials used for fixed partial denture (FPD) frameworks have had properties of excellent strength, durability, and biocompatibility. Some of the materials which have been used till date include alloys, ceramics, and high-performance polymers such as zirconia, Ni-Cr, lithium disilicate, and so on. All these, though excellent, have their advantages and disadvantages. Hence, the search has alway...

PURPOSE The aim of this study was to determine the influence of long base lengths of a fixed partial denture (FPD) to rotational resistance with variation of vertical wall angulation. MATERIALS AND METHODS Trigonometric calculations were done to determine the maximum wall angle needed to resist rotational displacement of an experimental-FPD model in 2-dimensional plane. The maximum wall angle...

The current scenario in dentistry proposes several treatment modalities for the esthetic and functional replacement of a congenitally or traumatically missing anterior tooth in young and adult patients which includes implant supported single crown, conventional FPD, Resin Bonded FPD (RBFPD) or RPD. However when certain clinical conditions or unwillingness of the patient preclude the replacement...
